The Lowdown
Alright folks, Rusty here. Let’s have a look at what Tarnos is serving up for the next couple of weeks. We’ve got a solid run of clean, fun surf coming our way starting this Saturday morning, and it’s looking like the best window of the whole outlook.
The action kicks off on Saturday the 29th of August. The morning is the clear standout for the whole period. The water is sitting at a very warm 75.2°, which is 5.0° warmer than average for this time of year – that’s a noticeable difference, you’ll feel it in your wetsuit (or lack of one). We’ve got a clean 6.2ft swell rolling in from the WNW, with a period of 9 seconds. That’s a moderate, punchy groundswell and the wave energy is solid at (641). The wind is a light offshore easterly at only 3 mph, so expect clean, lined-up waves. This is the pick of the entire forecast. The afternoon will chop up though, as a cross-shore wind builds in.
Sunday the 30th brings another fantastic morning. The swell drops a little to 5.2ft from the NW, but the period stretches to a juicy 10 seconds. Energy is still strong (490). The wind is glassy from the ENE at just 3 mph. The water is still feeling that warm anomaly. Sunday afternoon is a write-off with a howling cross-onshore breeze.
Monday the 31st is repeat business. A morning glass-off with 5.2ft NW swell (433 energy) and zero wind. Get in before lunch. Afternoon gets choppy again.
Tuesday the 1st of September and Wednesday the 2nd follow the same pattern: clean, glassy mornings with dropping swell (4.6ft and 3.0ft respectively), then choppy afternoons. The energy drops from (392) down to (105) by Wednesday, so the punch fades but it remains surfable for the dawn patrol.
Thursday the 3rd and Friday the 4th are flat and weak. The swell bottoms out below 3ft and energy is under 100. Not worth paddling out.
We get a second life on Saturday the 5th of September morning. A clean, glassy 3.6ft NW swell with a long period of 10 seconds and (273) energy. A nice little surprise to break up the flat spell, but the afternoon gets messy again.
Sunday the 6th of September morning is another glassy chance, with 4.3ft NW swell at 11 seconds and (414) energy. It’s a better swell than Saturday, but still just a morning window before the onshore wind hits.
From Monday the 7th through to the end of the outlook on the 13th, it’s largely poor. Onshore winds or onshore swell dominate, and the wave heights are either small or blown out. Wednesday the 9th of September morning offers a clean, cross-off breeze on a small 3.6ft NW swell (189 energy), but it’s ordinary at best.
The standout is without a doubt Saturday morning the 29th of August at Tarnos - La Digue. That WNW swell with clean easterly wind and warm water is as good as it gets in this forecast. Sunday the 30th morning and Monday the 31st morning are also very worthwhile for clean, fun waves. After that, it’s a case of picking the clean morning windows as the swell fades and the winds turn.
There is a significant gap of poor to flat conditions from Thursday the 3rd through Friday the 4th, and again from the 7th onwards. It’s a spot that can go quiet, so make the most of this first weekend.
Stay stoked.
